Yuu is freaking out. He hopes it's not too obvious, but he's pretty sure the only thing that saved him, is that Asahi is too much a coward to ask what was going on. He covered, but it wasn't a good cover. Daichi would be disappointed in him.
Now that Asahi is settled in front of him, he can let his face relax into it's true state of a total freak out.
He's alone. Alone with Asahi. Asahi is alone with him. In Asahi's house. Which is empty. Aside from them. Really looking at this reality, Yuu is actually marginally proud of himself for not just passing out earlier.
“Um, Nishinoya, is everything, um, alright?” Asahi asks.
